Love, love, love his sweet face! My Coco Puff has a slight case of CH and my Creamsicle was so bad in the beginning that I worried that I might have to do the unthinkable. I put ramps up in the house so that she could look out the window and pretty soon, she was able to scale them w/no problem and now she doesn't need them at all. She's still spastic but she's doing so much better. You've got experience w/it so I don't need to tell you anything but maybe Butterscotch will improve w/time. Let's hope so but either way, I'm sure he's a happy cat and he'll be oh so happy w/you!
